llviPROt/ENIENT IN STUIVIP'NIACHINES.

Specication forming part 01" Letters Patent N0. 115,055, dated January 5, 1364; antedated November 16, 1563.

To all whom it may concern,.-

Beit known that we, ArxIN E. BoYNToN, of Hartford, county of Vashington, State of -Wseonsin, and GEORGE R. BoYNroN, of the city of Chicago, county of Cook, State of Illinois, have invented new and useful Improvements on a Stump-Pulling Machine, (for which Letters Patent of the United States bearing date April 7, 1863. have been to us granted;)

and we do hereby declare that the following isA l'and use our invention, we will proceed to describe the construction and operation of the same.

A A, Fig. l, are two beams supported on posts B B, said posts resting firmly upon sills C C, the whole being secured rnily together by rods from the sills C C through the beams A A, secured on the top with nuts.

The frame D is formed of two planks, a cross-tie being framed across the front end, the back ends being bolted to the beams A A. The distance between the two sides ofthe frame D is just sufficient to receive the pillow-blocks E E and the bed h, the pillow-blocks resting upon both beams, while the bed h rests only upon the principal beam, being of suficient length to form a seat for the two fulcrums t" t, or the bed h may occupy the whole space between the sides of the frame D, the bed resting upon both beams, with an opening through it back of the fulcrum t" to admit the passage of'a cable to which the stu mp may be attached. The fulcruni z" is iixed in its seat in the bed h, and is to be used when great power is required. t is used for the purpose of gaining speed when the full power of the machine is not nec essary, and may be hung or used in any manner so it may be removed when not in use.

The frame D extends forward to support the liftingframe f, wheel m, axle a, and roller p.

The framef is used as a guide tothe end of the lever L, and also to raise the saine to a proper position for use. This is eii'ected by means of a rope or chain cable, r. Said rope is secured to the end of the lever L, on the under side, passing over the pulley p, back to the axle n, taking several turns around said axle, (being secured to it near A the center of its length,) thence over the roller near the crosshead of the framef, and again attached to the end of the lever L,on the upper side.

The wheel m is secured to the' journal n in the usual manner, (the whole being fastened on the top ofthe frame D,) and is used to apply power to and also operate the lever L by means of the rope, r, working on the axle n, raising or depressing the end of the lever as the motion ofthe wheel m is reversed. The pulley p serves as a leader for the rope r, and also to aid in loading said machine.

rIhe two fulcrums t" i are gaged in height, so that when the lever is raised to the full height t may be placed in position, as seen at Fig. 2. The end of the lever L being then brought down will rest upon the t'ulcrum i, then upon the lever being raised again t may be removed and the lever will then work upon i.

Fig.2 isalongitudinal elevation ofthe Wagon and apparatus for loading and carrying said machine, also a section of the lever L and frame D divided lengthwise through the center, showing plainly the internal arrangement of the same. For the purpose ot' loading and carrying said machine, we place upon an ordinary wagoirrack alight frame, S, to carry the end of the frame D, and upon the back end ofthe rack is placed pillow-blocks or bolsters c, of suflicient height to carry an axle clear of the hind wheels of the wagon. Upon the two outer ends of this axle is secured two Wheels, o. To the sills C is fastened at one or more points a rope or chain, x, or it may be secured to the center one of the posts B B B, thence passing over the wheels o,and secured to the periphery of said Wheels at w. The

hand-lever G is attached to the axle upon which the wheels o are xe'i, and when raised to the position as seen at Fig. 2 the chains a: are hooked onto the wheels o at w, then upon bringing down the lever G to a horizonta1 position the machine is lifted to a height proportionate to the size of the wheels o, and the lever being secured thus, the machine is easily transported. The lever G may, if necessary, be operated by a small rope Working over a pulley attached to the rack of the Wagon.

Vhat We claim as new and useful, being` our invention, is-

l. The use of two or more i'ulcrunis or their equivalents, when used for the purpose, and

substantially the same as herein specified.

2. The method of operating the lever L by a rope or cable in any manner substantially the same, when used for the purposes herein specified.

3. The manner of loading said machine for transportation on two or more Wheels, by attaching the chain x to any part of said machine, so that it may be lifted in any manner equivalent to our specification.
